Description of problem:
Can't deploy or execute VDB by JBDS with setting useDisk property to false.

Version-Release number of selected component (if applicable):
EDS 5.3.1

Steps to Reproduce:
1. Set following property to false;
 $JBOSS_HOME/server/default/deploy/teiid/teiid-jboss-beans.xml
 ~~
   <bean name="BufferService" class="org.teiid.services.BufferServiceImpl">
    <!-- Use disk for buffer management -->
      <property name="useDisk">true</property>
 ~~

2. Deploy or execute VDB whose size is 2.38MB by JBDS

Actual results:
Following ERROR was thrown by teiid server.

Expected results:

Additional info:
Original buffer size used in org.teiid.common.buffer.impl.MemoryStorageManager was initialized by MAX_FILE_SIZE(131072bytes) at L47. However, readWrite() tried to allocate more size to the buffer at L74.

org.teiid.common.buffer.impl.MemoryStorageManager.java
~~~
	public static final int MAX_FILE_SIZE = 1 << 17;  // L44
~~~
		private ByteBuffer buffer = ByteBuffer.allocate(MAX_FILE_SIZE);  // L47
~~~
		@Override
		protected synchronized int readWrite(long fileOffset, byte[] b, int offSet,
				int length, boolean write) {
			if (!write) {
				if (fileOffset >= getLength()) {
					return -1;
				}
				int position = (int)fileOffset;
				buffer.position(position);
				length = Math.min(length, (int)getLength() - position);
				buffer.get(b, offSet, length);
				return length;	
			}
			int requiredLength = (int)(fileOffset + length);
			if (requiredLength > buffer.limit()) {
				buffer.limit(requiredLength);   //L74
			}
			buffer.position((int)fileOffset);
			buffer.put(b, offSet, length);
			return length;
~~~

According to JavaSE7's javadoc, it's not allowed to assign a larger limit size  to the Buffer than it's capacity.
